Niagra Spawn Rate costs

Hey All,

I have a couple of Niagra systems that can be spawned/destroyed on demand.
(for rain, for exapmle)
Is there a difference between having the spawn rate = 0, compared to destroy the system alltogether?

Destroying the systems probably reduces costs, but results in all the particles disappearing right away, vs. changing the spawn rate to 0, which will result in a better look.

Thank you
